Django:AbstractBaseUser和Error ='AttributeError:无法设置属性'

Question

我是django的新手.我写我的django用户模型和用户管理器如下:

的UserManager:

class UserManager(BaseUserManager):
    def create_user(self, username, tel_number, password=None):
        """
        Creates and saves a User with the given email and password.
        """
        if not username:
            raise ValueError('Users must have an email address')

        user = self.model(
            username=self.normalize_email(username),
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, username, tel_number, password):
        """
         Creates and saves a superuser with the given email and password.
        """
        user = self.create_user(username, tel_number=tel_number,
                                password=password
                                )
        user.is_admin = True
        user.save(using=self._db)
        return user

我的UserModel是:

class Users(AbstractBaseUser, PermissionsMixin):
    object = UserManager()
    username = models.EmailField(_('UserName'), max_length=75, null=False, blank=False, unique=True)
    first_name = models.CharField(_('FirstName'), max_length=50, null=True, blank=True)
    last_name = models.CharField(_('LastName'), max_length=70, null=True, blank=True)
    tel_number = models.IntegerField(_('TelNumber'), null=True, blank=True)
    address = models.CharField(_('Address'), max_length=250, null=True, blank=True)
    user_image = models.ImageField(_('UserImage'), upload_to='user_avatar', blank=True, null=True)
    date_time = models.DateTimeField(_('DateTime'), auto_now=True, null=True, blank=True)
    activated = models.BooleanField(_('Activated'), default=False)
    is_admin = models.BooleanField(_('is_admin'), default=False)

    def __unicode__(self):
        return self.username

    def get_full_name(self):
        return self.first_name + " " + self.last_name

    class Meta:
        ordering = ['-id']

    @property
    def is_superuser(self):
        return self.is_admin

    @property
    def is_staff(self):
        return self.is_admin

    def has_perm(self, perm, obj=None):
        return self.is_admin

    def has_module_perms(self, app_label):
        return self.is_admin

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['tel_number']

现在我想创建超级用户我给出了这个错误:

句柄self.UserModel._default_manager.db_manager(database).create_superuser文件中的"E:\ AB - Python\Ads\lib\site-packages\django\contrib\auth\management\commands\createsuperuser.py",第149行.**用户数据)

文件"E:\ AB - Python\Ads\project\dijiads\users\models.py",第31行,在create_superuser中密码=密码

文件"E:\ AB - Python\Ads\project\dijiads\users\models.py",第19行,在create_user username = self.normalize_email(username)中,

文件"E:\ AB - Python\Ads\lib\site-packages\django\db\models\base.py",第470行,在 init setattr(self,field.attname,val)中AttributeError:无法设置属性

怎么了？
如果你有更好的建议写这个模型请告诉我.

您可以尝试删除:

@property
def is_superuser(self):
    return self.is_admin

来自Users课堂.is_superuser是permissionsmixin由用户类继承的字段.
